How the 3.7V 35mAh Micro LiPo Battery Pack Works
The 3.7V 35mAh Micro LiPo Battery Pack is based on lithium polymer technology, which uses a polymer electrolyte instead of a liquid one. This allows the battery to be lighter, thinner, and safer, making it ideal for compact electronics.
When charging, lithium ions move from the positive electrode (cathode) to the negative electrode (anode), where they are stored. During discharge, the ions flow back, releasing stored energy into the device. Thanks to this chemistry, the 3.7V 35mAh Micro LiPo Battery Pack provides a stable voltage output, which is critical for small electronics that need consistent power to operate correctly.
Its 1S (single-cell) configuration delivers a nominal 3.7V output, which is perfect for most wearables, micro drones, and IoT devices. With a max charge/discharge rate of 1C, it balances fast charging capability with long-term cycle life.
Comparison with Other Battery Types
When selecting a battery for small electronics, it’s important to compare different technologies. The 3.7V 35mAh Micro LiPo Battery Pack stands out against several alternatives:
LiPo vs. Coin Cell Batteries
Coin cells are inexpensive and widely used, but they are non-rechargeable and offer limited capacity. In contrast, the 3.7V 35mAh Micro LiPo Battery Pack is rechargeable and provides a much longer lifespan, making it more cost-effective and eco-friendly.
LiPo vs. Li-ion Batteries
While both use lithium chemistry, Li-ion batteries often come in cylindrical or rectangular forms that are bulkier and heavier. The 3.7V 35mAh Micro LiPo Battery Pack offers a slimmer and lighter profile, which is essential for wearables and micro devices.
LiPo vs. NiMH Batteries
